Enables AI agents to detect and verify the language of texts, run bundle checks, and top up prepaid credits by paying per call in USDC on Solana, with no account, API key, or subscription needed. Payment is handled transparently via x402 challenges, prepaid credit tokens, or a funded payer wallet with sponsored gas.

A local-first MCP server for the WAX blockchain that enables AI hosts to query accounts, chain state, AtomicAssets, AtomicMarket, Hyperion history, and WAXP prices, as well as prepare unsigned transactions for wallet signing.

Provides MCP tools to disassemble Kaspa scripts, estimate compute costs, explain txscript errors, and look up opcodes.

Enables MCP clients to get swap quotes and calldata on Robinhood Chain with equity-aware guardrails such as oracle fair-price checks and market-hours warnings, without holding keys or executing transactions.

Enables AI agents to enforce configurable spending policies before executing trades or x402 payments via Binance Agent OS, recording every policy decision onchain to an Ethereum Sepolia audit log.

Combines Midnight Network blockchain development tools with Next.js DevTools for building decentralized applications, supporting contract development, wallet management, and Next.js diagnostics.

Use the microservice of testraptor

Enables an AI assistant to inspect, validate and step-debug Cardano transactions and Plutus scripts, including finding failing redeemers, explaining ledger/CBOR/CDDL errors, decompiling UPLC, and opening highlighted problems in cquisitor or de-uplc-web.

Prepares unsigned App/PWA handoffs for creating positions in Denaria markets, returning QR codes for user review and signing in the Denaria app, without signing or executing transactions.

A Model Context Protocol server that enables AI assistants to access Flow blockchain data and perform operations such as checking balances, resolving domains, executing scripts, and submitting transactions.

Enables AI agents to make pay-as-you-go AI inference requests through x402 with automatic Solana USDC payments, no API keys or registration, while enforcing configurable spending limits.

Keyless crypto payments for AI agents. One MCP call turns any wallet address into a non-custodial crypto payment link or tip jar, no API key and no account, with funds settling straight to your wallet at a 0% platform fee (USDC/USDT, BTC, LTC, DASH, DOGE, ZCASH).

Resolves a company name, registrable domain, or LEI to its GLEIF legal entity record — LEI, legal name, jurisdiction, entity status, and registration status — for $0.05 USDC on Base paid per call over x402, with no signup or API key. Includes a free, no-wallet preview of price and coverage plus hard per-call and per-session spend caps, while misses and ambiguous matches cost nothing.

Enables static security audit of Solidity smart contracts by analyzing source code or deployed bytecode for vulnerabilities, providing risk scores and detailed findings.

Quick-scan a smart contract for rug, honeypot, or centralization risk before sending funds. It combines verified source, live on-chain state, and heuristic Solidity analysis to return a SAFE/CAUTION/HIGH-RISK verdict.

Universal x402 buyer agent — discover, pay for, and call any x402 paid API endpoint from Claude Desktop, Cursor, or Claude Code with automatic USDC payment via AgentCash.

Enables an AI assistant to read token bonding curves, quote trades with fee breakdowns, monitor graduation progress, and optionally launch, buy, sell, or rescue tokens on Arc via arcnow.io.

MCP server that scores the behavioral risk of a wallet on Base before sending it money. Provides a risk score, verdict, and explainable flags based on USDC payment history.
